Ford 302 - Intake bolt broke off in the head

Just as the title says - i was removing the intake from my 87 F150 (302) and the front passengers side bolt snapped off. The head snapped off and then while trying to remove the intake (figured with the bolts straight up and down on the 5.0s, and the head of the bolt being broke off that the intake would lift straight up and come off. Wrong! It broke the bolt off again. So I have the head of the bolt, part of the bolt stuck in the intake, and part of the bolt stuck in the head Bolt is not sticking out of the head at all so welding to it is not an option.

I fear I will be pulling the head and taking it to a machine shop

Im going to try PB blaster for a couple days. and maybe drill a hole in the bolt and try an extractor, but i wont put much effort into that because I dont want to make it worse or impossible for the machine shop to remove.

I guess what I would like to know is if i can take a torch and heat up the head around the bolt and see if i can get it out with the extractor then? Or will heating the head cause damage to it? Especially if we are talking RED HOT kind of heat - which is usually the kind of heat it takes to remove a stuck bolt.
